Of course there's no need to re-spool Polymaker filament... Just peel one cardboard side away down to the core, slide the Bambu spool into the core, then flip it over, peel away the cardboard on the other side, and put the other half of the Bambu spool on... Fast, easy, no re-spool necessary. This also works for Elegoo cardboard spools, and a few others... Just when you peel the first side of, make note of which side of the core has the notch cut into it so you use the correct Bambu half on the notch side, and only remove one side at a time... You never want to remove both cardboard sides without first having the Bambu spool in place on one side
The difference in prints between the Bambu and the Kobra isn't the printer, it was your filament... The white has a lower maximum volumetric flow rate than the grey, so you were basically trying to print faster than the hotend could melt the filament on the Kobra, resulting in under-extrusion.
It is, but the ones I printed either cracked, slipped, or bent the cardboard trying to put them on. I printed 6 and ended up tossing them all the the recyling bin...
@@3DPrints747 maybe they need to be scaled up. I gave a colleague with an AMS a spool of Polymaker and the STL, he printed the rim in TPU and used the spools without issues
This is an awful idea, specially if you use an electric drill to re-spool your filament. If you really need to re-spool it, first you need to at least heat up your filament, if not, your will expose it to stress and compression forces that will break it in the future. It's already happening to a lot of other users that tried to respool their filaments
What are your sources for this information? I'm interested. The more I get into 3d printing the more I want to learn about various aspects of mechanical engineering as it applies to printing

Isn't it easier to print a TPU or ABS rim for the Polymaker spool, so that it can work on the AMS without wear/dust?

I just wish companies would stop using cardboard reels.

That's good info. I'll definitely look into it! Thanks!!!
